Raleigh prep guard Graham picks Jayhawks

RALEIGH — N.C. State came in a disappointing second to Kansas on Thursday when the nation’s top remaining uncommitted prep player, guard Devonté Graham of Raleigh, chose to cast his lot with the Jayhawks.

Pack fans hoped Graham would help ease the loss of rising junior guard Tyler Lewis, who started 18 games last year, but has transferred to Butler.

The school announced Friday that Allen has been granted a request to be released. In two seasons with Maryland, Allen averaged 10 points and 2½ assists over 56 games.

The Terps are joining the Big Ten Conference this summer.

BOSTON — The Boston Bruins and Mayor Marty Walsh condemned racist slurs about P.K. Subban that hit social media after the Montreal defenseman scored in the second overtime of their playoff game Thursday night.

Bruins President Cam Neely issued a statement Friday calling the tweets “racist” and “classless.” He said they came from an “ignorant group of individuals” who do not reflect the organization.

Subban, who is black, scored twice and the Canadiens won 4-3 to take a 1-0 lead in the best-of-seven Eastern Conference semifinals.

Lee, Masson lead LPGA Shootout

IRVING, Texas — Meena Lee shot a season-best 64 that included a nine-hole stretch without a par and Caroline Masson had her second straight 67 to share the lead in the North Texas LPGA Shootout.

At 8-under 134, Lee and Masson were stroke ahead of Texan Stacy Lewis and Natalie Gulbis.

The 65 on Friday for Gulbis was her first sub-70 round this season, putting her in contention for her first victory in seven years. She is playing with an achy left wrist, and has an appointment with a specialist next week to finally figure out what is causing the pain.

Lewis, the No. 3 player in the world, had a bogey-free 64 to match Lee for the best round of the day. Christina Kim was 6 under after a 69.
